Are Microsoft, Apple and Google quietly preparing for war with mobile carriers? I think so. With all the advancements in mobile phones in the past 10 years, the part that’s been woefully slow to advance is the phone part. Making calls, placing calls, searching for signal and scrimping minutes hasn’t changed much since the phone came out, because carriers have little motivation for innovation.

Me too. I just dropped my landline phone last year, and I am amazed that I can stream videos and music on my cell phone, but the actual voice quality of calls sounds worse than on landline. Shouldn't the quality of voice calls be better, especially on high end smartphones?
